Our 3 Technical Advantages

Tri-namic Blade Profile

This is our unique blade design that brings together three key performance features in a single blade profile.  What makes it Tri-namic?

  1. The Rutland 1200 model maintains our reputation for turbines with a very low windspeed start up – this means that we capture energy from the lowest and most commonly experienced wind flows so you can rely on your Rutland for the energy you need.
  1. The finely designed blade profile remains almost silent across all wind speeds so you can rest assured that you and your neighbours will not be disturbed by aerodynamic noise. We have benchmarked this important feature against existing competitors and the Rutland 1200 is the quietest in the market.


  1. It’s powerful – in high winds the Rutland 1200 blade achieves high rotation levels thus delivering more power than any other turbine of its diameter range at 3, 6, 12 & 15m/s (6, 12, 23 & 29Knots)

We congratulate our design team because this is a real first that we know of, no other micro wind turbine brings together all 3 features to benefit the user from excellent power generation combined with silent running whether it’s just a gentle breeze or a stiff wind.

Powerful Turbine Generator

The vast experience at Marlec shines through in our new rare-earth magnet generator.  Rare-earth magnets are the strongest type of permanent magnets manufactured.  They produce significantly stronger magnetic fields than other types and require careful handling but pay back swiftly in the power they are able to induce.

Low friction is critical to low wind speed performance and we have taken these super strength magnets into our new design of brushless generator yet maintained low wind speed start-up.  The Rutland 1200’s supporting structure, called the nacelle, is constructed of high quality marine grade materials such as a stainless steel shaft.  The sleek outer casing is made from lightweight but robust mouldings to a high UV resistance specification which contrasts the distinctive blue anodised generator casing.

State of the Art Controller Included

Maximum Power Point Tracking technology is used on both the wind turbine and solar panel inputs to electronically boost the power outputs, charging your batteries faster.  The controller intelligently controls the inputs and battery voltage to give efficient charging and fine battery voltage regulation and maintenance.

Input capacity of the unit is high, accepting both the Rutland 1200 with up to 20A of solar panels, that’s 250W @ 12V and 500W @ 24V.   Outputs to 2 battery banks make this an ideal solution for keeping batteries charged on sailing yachts.

Speed governing of the turbine occurs electronically from the controller, this becomes active at 15m/s or 29Kn or 35mph.  This intermittently alters the speed of the turbine to reduce aerodynamic and electrical stresses on the system.

A remote digital display available now.  The controller has built in LED indicators and shutdown switches for the charge inputs.

Performance of the Rutland 1200

We publish our curves based on measured data and use ongoing actual performance data collected and monitored over long periods of time of the turbines running in clear and real wind conditions. This means the turbines are also subject to side winds, upwinds and sudden changes of wind direction (these are the causes of turbulence) experienced at a user’s typical installation. Our curves represent a truer reflection of the power output you can expect from your Rutland Windcharger compared with many other turbines.

A power curve is usually given by manufacturers to represent the performance of a wind turbine. Some may be based on theoretical or predicted output and others plot the power achieved under steady state conditions. Wind tunnel testing and turbines run on vehicle rooftops can provide useful information for a manufacturer but power curves derived in this way need to be understood as running in a clear and unobstructed wind flow so they do not represent what is actually achieved in real wind conditions. Power curves from theoretical analysis cannot be regarded as representing what is actually achieved at all.

A more useful guide of how much power you can expect from your turbine is the Annual Energy Yield. That’s because wind energy is a “cube law,” which means that when the windspeed doubles the power potential is 8 times! Check the Annual Energy Yield bar chart which uses the Rayleigh distribution to calculate the Ampere hours of battery charging you can expect at given average wind speeds per annum. As these are averaged across the year you should consider how these figures will ebb and flow across the seasons when you might expect a higher average during the windier seasons. We often recommend the combination of wind and solar charging to smooth out the daily energy yield.

  1. Dean Adams (verified owner)

    Finally having installed my Rutland 1200 after months of lockdown, I found that I needed a non-standard length of steel for one of the stays. Contacted Rutland, and Stuart James, the Business Development Manager, sorted things out for me – no problems at all, just as he had already done when I couldn’t get hold of the thick 3-core wiring. All fitted and I’m really pleased with it. Can’t recommend Marlec enough for the quality of the product and their customer care. Really great to see such a good British company,

  2. Steve Benn

    Following problems with ‘low mast height’ due to mounting difficulties I contacted Marlec, my call was returned by Stuart James, the Business Development Manager who after discussions agreed to supply a non standard extra length section to overcome problems. Excellent customer service.

  3. J Doran

    Hi just to let you know that the Rutland 1200 Windcharger survived the hurricane Ophelia and worked very well and controlled it self very well.

  4. John & Pam Batson

    We’re now out living aboard enjoying the boat and can honestly say we are delighted with the performance of The Rutland 1200 Wind Generator. Teresa and David were both so helpful.

  5. Helen & Chris

    With the solar panels we bought from you and the wind generator we are managing well at anchor here , we will certainly be singing your products praises to other possible World Arc participants as the areas are so remote that you have to be self sufficient for energy.

    As potential purchasers there is a tendency to take the marketing stuff from various manufacturers with a pinch of salt. In this case i think the Rutland 1200 does EVEN BETTER than their publicity. Superb. So quiet i need to look up to see if it is working. A friend of mine has a windgen from guys who reckon they have the most “silent” and i have sailed about 1,500 Nm on his yacht. Makes so much noise he has to shut it down to get some sleep. I love the Rutland 1200, so quiet.

    From consulting and advising prior to the purchase through to commissioning on our 5th Wheel Caravan the Marlec Team has been absolutely outstanding. The Rutland 1200 is powerful yet quiet and now allows us to camp ‘off the grid’ with the confidence of knowing in virtually any wind our batteries are being fully charged. Topping it off being able to monitor the output from the Remote Display from inside our unit is fantastic, thank you again Marlec!

  8. Christopher Brunt

    First real test of the Rutland 1200 crossing Biscay in Light conditions I have only had to use my engine once and that was to make hot water! The Rutland 1200 has more than kept up with my power demands and it starts up in such light winds which only makes me think that it is windier than it actually is ! Excellent product I can well recommend .

  9. P Landino (E-Marine Systems)

    We’ve had two of our recent customers return their purchased turbine from another manufacturer to be replaced with the 1200. I think that’s a good sign.

  10. H Tibbs

    The wind Charger is absolutely brilliant WE LOVE IT !! In Fact Chris just sent an article to Yachting World and gave The Rultand charger very positive coverage. We have had varied weather and loads of wind 35knt whilst we were in Baiona and she just kept wizzing nicely . We have a nickname for the charger and have called her Twirley . It is so nice not to have to use the engine to charge the batteries . We are running two fridges and two chart plotters and all the instruments and haven’t had to run the engine for charging at all .

  11. J Delisky

    So that you know it was a tough decision between the 1200 and what seems to be the most popular unit in the Caribbean, the D400. Typically I avoid new products but made an exception in this case. This was based very much on your company’s reputation with previous units. My decision has been confirmed by the support you’ve provided. I’ll certainly advocate the Rutland 1200 and Marlec moving forward. Thanks again!
